My req fuel was probably too high, but I am going to keep it where it is right now and just tune.
I think I have a spare vtps I will try to hook up, but yes it will creep up and then when I was trying to calibrate it, it resets the ecu and cuts off like you described. I suspected that might be it.
Now when I install the Vtps, do I still need to cut the wiring, or can I keep the wiring the same?
EDIT: I think I found my answer on the tech. I really hate cutting wiring though...

TPS / Idle Air Control / Acceleration Enrichments
This model does not have a variable TPS, rather an on/off style. As a result the IAC type will need to be set to "PWM Warmup" as well as the standard Accel Enrichments (not Enhanced) used.
Until a variable TPS is added, TPS SIG from the Main Board will need to be jumpered to Ground with a 1k Ohm resistor to prevent the TPS signal from gradually floating higher and possibly accidentally triggering flood clear mode.
The addition of a variable TPS will allow the use of Closed Loop Idle Control as well as Enhanced Acceleration Enrichments as both of these features look to the TPS signal for feedback. If you add a variable TPS, pin 52 connects to pin 1 (brown / blue wire) on the factory TPS wiring, and pin 53 connects to pin 3 (brown / black wire). The brown center wire of the TPS connector is grounded. We are not aware of any off the shelf TPS that matches the connector and pinout, so you will need to do some wire splicing.
